Scientists Scour Genome For Clues About Disease

The reason some of us get diseases such as cancer or diabetes while others don't may lie in our DNA. This hour, we'll look at the genetics of common diseases, including a new study that links variations in DNA to differences in how well different people fight HIV infection. New technology in genetics has allowed researchers to sift through the human genome looking for possible genetic connections to all types of diseases. But how can knowledge about those associations be put into use? We'll talk with several key researchers in the field of genome-wide association studies.
